- The presidents daughter, Yoon Jae-hee (Jun Do-yeon) is living in Prague working as an official in the consulate under foreign affairs. Choi Sang-hyun (Kim Joo-hyuk) is a detective who goes to Prague in order to look for his girlfriend, Hye-joo (Yoon Se-ah). Sang-hyun who loves Hye-joo very much has been paying for Hye-joo's tuition, and was planning to marry her in the future. However one day, after Sang Hyun receives the presidential letter of commendation, Hye-joo (who is in Prague) tells Sang-hyun never to look for her again.
Sang-hyun ends up going to Prague to find Hye-joo. Sang-hyun meets Jae-hee and misunderstandings arrive between them. Sang-hyun ends up thinking Jae-hee is a prostitute but later asks her to help him translate (because he only spoke Korean) when he gets into a little problem with a pick-pocketer. Coincidentally, Jae-hee's roommate is Hye-joo. Later, Sang-hyun learns that she is pregnant with another man's baby. Hye-joo tells Sang-hyun she loves the other man even if he is much older because he is wealthy. Ji Young-woo (Kim Min-joon) is from a prominent family, he was Jae-hee's former boyfriend, but had left her due to his own reasons, and still harbors feelings for her.
Apparently, Young Woo's father was the man who got Hye Joo pregnant!
3 months later, back in Korea, Jae-hee gets pulled over for speeding. The officer who pulled her over is Sang-hyun...the two then form a love story.
